Specification of Letters Patent.

Patented Mar. 12, 1918.

Application filed October 19, 1916. Serial No. 126,528.

To all whom it may concern: 7

Be it known that I, JOSEPH B. FERGUSON, a subject of the King of Great Britain, and a resident of the city of New York, county and State of New York, have invented certain new and useful Improvements in Engines, of which the following is a specification.

This invention relates to engines, and particularly to the arrangement of the accessories of an internal combustion engine with relation to'each other and to the engine, whereby the inherent and incidental characteristics thereof may cooperate to produce a useful and desirable result.

An object of this invention is to arrange the accessories of an internal combustion engine in such relation to one another, and to the engine that certain characteristics of said accessories and engine which are undesirable shall be neutralized and turned to advantage.

Another object is to arrange the accessories of an internal combustion engine in such relation to one another and to the engine that certain of said accessories shall be incased with the engine and concealed and protected. In the attainment of this object and as a further object, it is my object to kee such accessories from becoming overheated by radiation from the engine or from internal heating, and from becoming moist by taking away such heat or moisture in an air stream, and preferably preheating the fuel mixture, the air being circulated preferably by the suction of the carbureter or by a moving part of the engine.

Other and further objects and advantages will appear from the following description taken in connection with the accompanying drawings forming a part of this specification, and will be pointed out in the hereunto appended claims.

In the drawings, in which like reference characters indicate similar parts,

Figure 1 is a partial elevation of an engine embodying my invention, with parts removed;

Fig. 2 is a partial plan view of the engine shown in Fig. 1; and

Fig. 3 is a transverse section of the engine shown in Fig. 1.

The engine herein illustrated and described is to be considered as one embodiment of my invention, and as being disclosed in detail for the purpose of interpreting my invention; and it is to be unerstood that my invention is not to be limited to the specific details thereof, but is to be defined by the hereunto appended claims.

The engine comprises a crank casin made up of the parts 1 and 2 and the cy inders which are covered by casing 3. U on the.

ortion 2 of the crank case a shelf-like proection 4 is formed. The shelf-like projection 4 and the cylinder casing are shaped to provide a chamber 5 in which there are positioned the enerator 6 and the starting motor 7 The e ectrical devices are partially covered by a housing 10 which has in it a large opening which is normally closed by cover plate 11 held down by nut 12 which engages thethreaded end of the stay-bolt 13 which is mounted in the engine frame. The forward part of the chamber which partially surrounds the engine consists of the portion 15 which extends part way across the front of the engine, and the removable portion 16 which extends the re mainder of the distance, and which comprises the housing for the magneto 17. Ihe portion 16 is made removable, and it is apparent that by removing the cover plate 11 and the portion 16, all of the electrical devices can be inspected and adjusted.

The chamber opens at its rear end into the housing 18 of fiy-wheel 19, and the housing 18 has on the other side of the engine an opening which is connected by pipe 20 to the air intake of the carbureter 21. The chamber is provided with openings 22 which are formed in the portion 17, and openings 23 which are formed in the portion 10. When the engine is in operation, the rotation of the fly-wheel, as well as the suction of the carburetor, will cause a circulation of air into the openings 22 and 23 and through the chamber and across the electrical devices therein. The accessories, including the electrical devices of an internal combustion engine, should be incased to as great an extent as possible, and should be firmly attached to the engine for purposes of protection and convenience; and by providing a chamber formed on the engine frame through which air is caused to circulate, I am able to mount the accessories right on the frame'of the engine and at the same time withdraw from them by circulation of air, the excess of heat which reaches them by reason of radiation from the engine, and by reason of inherent self-production oi heat, as in the case of a starting motor or generator; and the circulation of air also prevents the accumulation of moisture in the electrical devices. The circulation of air may be brought about by the movement of the fly-wheel or a fan driven by the engine, or it may be brought about by the suction of the carbureter, and in the latter case the withdrawal of heat from those accessories which it is desired should be kept cool, results in a preheating of the air for the fuel mixture. By reason of the circulation of air in thechamber, there is a slight negative pressure, and I therefore provide communication between this chamber and the crank case by means of a crank case release vent 30, so that a negative pressure exists in the crank chamber and oil is not thrown out through the valve tappet openings. The chamber being provided with sharp corners 31, any dust contained in the air will be caught by reason of the rapid circulation of the air in the chamber, and will not flow into the carbureter.

It will be apparent from the foregoing that I havearranged the accessories of the internal combustion engine so that the undesirable features are neutralized and turned to advantage.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In an internal combustion engine, a crank casing, a fly-wheel casing, a chamber formed upon said engine for inclosing elee trical accessories of said engine and communicating with said fly-wheel casing, and a carbureter for said engine havin its air intake communicating with said y-wheel casing.

2. In an internal combustion engine, a crank casing, a fly-wheel casing and a chamber formed upon said engine for inclosing electrical accessories of said engine and communicating with said fly-wheel casing, said fiy-wheel casin having an outlet opening whereby the action of said fly-wheel will circulate air through said chamber.

3. In an internal combustion engine, the combination of a crank casing having a plurality of cylinders mounted thereon, a shelf projecting from the longitudinal side of said casin and having a cover providing a closed cham er therewith, electrical accessories within said chamber, air inlets at one end of said chamber and a carbureter connected to the other end of the chamber whereby air for the carbureter is preheated and cools the accessorles.

4. In an internal combustion engine, having a crank casing and cylinders mounted thereon, a chamber formed upon said casing of the engine and extending along the side thereof, electrical accessories for said engine and positioned within said chamber, and a carbureter for said engine and having its air intake communicating with said chamber, said chamber being closed except for openings admitting air at points where the air will be drawn across said accessories by said carbureter to cool said accessories.

5. In an internal combustion engine, a chamber formed upon the casing of the engine, electrical accessories for said engine and located in said chamber, and a carbureter for said engine and having its air intake communicating with said chamber, said engine having a crank case communicating with said chamber, substantially as described and for the purpose specified.

6. In an internal combustion engine, a chamber formed upon the casing of the engine, electrical accessories. for said engine and inclosed in said chamber, and means for withdrawing air from said chamber, said engine having a crank ease in communication with said chamber, substantially as and for the purpose described.

7. In an internal combustion engine, a chamber formed upon the outside of the casing of the engine for inclosing electrical accessories of the engine and extendin partly therearound and comprising a shel like portion extending out from the frame of said engine and cover portions resting on said shelf-like portion and forming therewith said chamber.

In testimony whereof, I have signed my name to this specification.
